Facebook SSO

Hey Everyone,

I was wondering if anyone else was getting an "Apple Match -O Linker Error" when they add the newest Facebook SDK to their Xcode project? For me it is saying

Quote:

ld: duplicate symbol _OBJC_IVAR_$_SBJSON.jsonWriter in /Users/ND/Library/Developer/Xcode/DerivedData/BandManager-emqnzeoaiawijecbtplbztwhtdzl/Build/Intermediates/BandManager.build/Debug-iphoneos/BandManager.build/Objects-normal/armv6/SBJSON-7540B5C521D0446C.o and /Users/ND/Library/Developer/Xcode/DerivedData/BandManager-emqnzeoaiawijecbtplbztwhtdzl/Build/Intermediates/BandManager.build/Debug-iphoneos/BandManager.build/Objects-normal/armv6/SBJSON-3ED40C1A4992D586.o for architecture armv6

If I remove the Facebook SDK folder from my project the error goes away, and when I add it again it shows up. I've tried cleaning and doing a build folder clean and I'm running out of ideas. Any input would be appreciated!

Thanks.

Yes I am using Ben Gottlieb's Twitter with OAuth - which wraps MGTwitterEngine - https://github.com/marksands/Twitter-OAuth-iPhone

But I don't see a declaration of another SBJSON class unless it is inside one of the libraries it uses.

Actually found it in the Dropbox SDK! Thanks for your help!
